“Folks, you let that be George W. Bush, you let that be Ronald Reagan, and the stories today are, ‘Is Alzheimer’s setting in? Do we have dementia?’ I’m not kidding,” Limbaugh said. “They would have psychiatrists and psychologists on TV, and they would be analyzing this, and they’d be looking for any indication that a declining mental capacity is taking place.”

The radio host called out the president over his geography gaffe made during his late-night TV appearance with Jay Leno.

Limbaugh also mocked Obama for apparently forgetting the name of Vice President Joe Biden’s wife. “He didn’t remember her name, and that means probably that the teleprompter froze,” he added.
